Please tell me that you aren't using R and R RV sales out of Gillman.....
They really don't know the product that well and I found a place near the factory that was a bit over $1000.00 less.
The Safari upgrade pkg includes:
Screen guard (for the screen door)
Aquajet pump upgrade
LED tail lights
Upgrade from 11k BTU a/c to 13.5k BTU A/C (for $200 the 15k BTU is the way to go when going that large)
Caps and Jacket (2)
I think there was 1 or 2 more, but I don't have my paperwork handy....
As for the custom job, I know it seems easy, but I gotta tell you, so was adding the CCD window in place of the emergancy only rear window in the Safari. Same size, same location, the answer was no....... I'd call Airstream to confirm either way.....
Where in Chicagoland are you?
